Espionage has been practiced and thought of since antiquity. According to Sun Tzu, in The Art of War, it is an act only allowed between belligerents, nations, guerrilla groups in war and/or guerrillas. It has been part of what we normally call Intelligence, and consists of the practice of obtaining confidential information related to governments or organizations, without their authorization, to obtain a certain military, political, economic, scientific, technological and/or social advantage. The practice usually manifests itself as part of an organized effort (that is, as the action of a government or business group). A spy is an agent employed to obtain such secrets. The definition has been restricted to a State that spies on potential or actual enemies, primarily for military purposes, but it also covers espionage involving companies, enemies between them, competitors and in "guerrilla warfare"; in (known as industrial espionage) and individuals, through hiring private detectives, whenever espionage there is a dispute. The activity has specific spy devices, such as hidden cameras, wiretaps and many others. In nautical, a spy is a type of cable that is also called boça and serves to tie a ship to another, in order to tow it, it is always a cable of great caliber. According to Marcelo de Montalvão, in Intelligence & Industry: Espionage and Corporate Counterespionage, "The Intelligence Activity or Information Service or Secret Service or Espionage is the implementation of a data and information collection system to identify threats and opportunities for an organization with the scope of helping the leader or decision makers in the elaboration of strategic plans or execution of tactical and operational actions of attack, maintenance and defense of that organization. Information is the product result of the systematic work of collection, analysis and delivery of data and information called Intelligence Activity".
